This device offers high mixing efficiency, and the installation and removal of sample vials are simple and convenient.
[0004] The above-mentioned mixing machine has the advantage of easy and convenient disassembly of sample bottles. However, when the existing mixing machine is used to mix and fill coal, the limitations of the mixing seat bottle opening cause problems such as filling difficulties and scattering and contamination of the mixing machine. At the same time, a large amount of dust is usually generated when the coal is transferred, which affects the health of the operators. Therefore, there is a need to provide a coal mixing machine for mining machinery. Summary of the Invention
[0005] The purpose of this utility model is to provide a coal mixing machine for mining machinery to solve the problems of difficult filling, coal scattering, and the generation of a large amount of dust that affects the health of operators in existing mixing machines.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a coal mixing machine for mining machinery, comprising a workbench and a drive motor, two fixed rods rotatably mounted in parallel on the workbench, a mixing seat fixedly mounted between the two fixed rods, and a combination mechanism provided on the mixing seat; the combination mechanism includes a transfer bottle, one end of which is threaded with a sealing cap, and the other end of which is fixedly mounted with a first insert tube, and both ends of the mixing seat are fixedly mounted with second insert tubes, a connecting seat is sleeved between the first insert tube and the second insert tube, and two rubber rings are fixedly mounted on the upper and lower sides of the inner wall of the connecting seat.
[0007] Preferably, the outer surfaces of the first and second inserts each have two annular grooves arranged side by side, and the rubber ring is adapted to the annular grooves.
[0008] Preferably, the mixing seat is S-shaped, and the inner diameter of the sealing cap is 1.5 times the inner diameter of the first insert.
[0009] Preferably, a material injection mechanism is provided between the first and second insert tubes. The material injection mechanism includes an injection seat, which is fixedly installed inside the first and second insert tubes. A material control seat is rotatably installed inside the material injection seat. A limit seat is fixedly installed on the upper side of the material control seat. A buffer spring is fixedly installed between the material control seat and the material injection seat. A limit rod is fixedly installed inside the connecting seat.

[0011] Preferably, the inner diameters of the limiting seat and the rubber plug are the same, and both the limiting seat and the rubber plug are adapted to the limiting rod.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1) This coal mixing machine for mining machinery adds appropriate amounts of coal to different transfer bottles, and then connects the coal-filled transfer bottles to the mixing seat in sequence. In use, both the first and second inserts are embedded in the connecting seat to complete the combination of the mixing seat and the transfer bottles. After the coal is added, the transfer bottles are pulled out to control the drive motor to rotate the mixing seat to mix the coal. After the coal is mixed, the transfer bottles are inserted into the connecting seat to transfer the coal inside the mixing seat. The mixing machine does not need to add coal directly into the mixing seat, thus avoiding coal contamination of the mixing seat and increasing the flexibility of the mixing machine.
[0014] 2) This coal mixing machine for mining machinery uses a control limit rod that is embedded in the limit seat inside the first and second inserts respectively. By further rotating the connecting seat, the control seat rotates within the injection seat, opening the gap between the first and second inserts, thus allowing coal to transfer between the mixing seat and the transfer bottle. After the coal transfer is complete, the control seat will reset under the action of the buffer spring. At this time, the mixing seat and the transfer bottle are separated, and the rubber stopper is placed on the limit rod. The mixing machine is easy to operate and has no coal leakage throughout the process, greatly increasing its environmental friendliness. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model. Embodiments
[0021] Referring to Figures 1-4, a coal mixing machine for mining machinery includes a workbench 1 and a drive motor 2. Two fixed rods 3 are rotatably mounted side by side on the workbench 1, and a mixing seat 4 is fixedly installed between the two fixed rods 3. A combination mechanism 5 is provided on the mixing seat 4. The combination mechanism 5 includes a transfer bottle 501, one end of which is threaded with a sealing cap 502, and the other end of which is fixedly installed with a first insert tube 503. Both ends of the mixing seat 4 are fixedly installed with second insert tubes 504. A connecting seat 505 is sleeved between the first insert tube 503 and the second insert tube 504. Two rubber rings 506 are fixedly installed on the upper and lower sides of the inner wall of the connecting seat 505.
[0022] Referring to Figure 3, it is further seen that the outer surfaces of the first insert 503 and the second insert 504 are each provided with two annular grooves in parallel, and the rubber ring 506 is adapted to the annular grooves. The shape of the mixing seat 4 is S-shaped, and the inner diameter of the sealing cover 502 is 1.5 times the inner diameter of the first insert 503.
[0023] Specifically, coal is added to the transfer bottle 501 by removing the sealing cap 502, and then the transfer bottle 501 is sealed again with the sealing cap 502. The first insert 503 is then inserted into the connecting seat 505, and one end of the connecting seat 505 is fitted onto the second insert 504. This completes the combination of the mixing seat 4 and the transfer bottle 501. After the coal transfer is complete, the first insert 503 can be removed to use the mixing seat 4 for further mixing of the coal. Adding coal to the mixing seat 4 in a distributed manner avoids coal spillage and contamination of the mixing machine. Example
[0024] Referring to Figures 1 and 4, an injection mechanism 6 is provided between the first insert tube 503 and the second insert tube 504. The injection mechanism 6 includes an injection seat 601, which is fixedly installed inside the first insert tube 503 and the second insert tube 504. A control seat 602 is rotatably installed inside the injection seat 601. A limit seat 603 is fixedly installed on the upper side of the control seat 602. A buffer spring 604 is fixedly installed between the control seat 602 and the injection seat 601. A limit rod 605 is fixedly installed inside the connecting seat 505. Columns 606 are fixedly installed at both ends of the mixing seat 4. A buckle 607 is rotatably installed at one end of the column 606. A rubber plug 608 is fixedly installed at one end of the buckle 607.
[0025] Referring to Figure 4, and based on Embodiment 1, it is further found that the injection seat 601 is composed of a semi-circular frustum, the control seat 602 is composed of a 3 / 5 disc, and the control seat 602 is embedded and rotatably installed in the injection seat 601. The inner diameters of the limiting seat 603 and the rubber plug 608 are the same, and both the limiting seat 603 and the rubber plug 608 are adapted to the limiting rod 605.
[0026] Specifically, by controlling the limiting rod 605 to be embedded in the limiting seat 603 inside the first insert 503 and the second insert 504 respectively, the first insert 503 and the second insert 504 are further embedded in the connecting seat 505. By rotating the connecting seat 505, the material control seat 602 can be rotated in the filling seat 601, and the gap between the first insert 503 and the second insert 504 will be opened, thereby allowing coal to be transferred between the mixing seat 4 and the transfer bottle 501. After the coal transfer is completed, the material control seat 602 will be reset under the action of the buffer spring 604. At this time, the mixing seat 4 and the transfer bottle 501 are separated, and the rubber stopper 608 is sleeved on the limiting rod 605.
[0027] In actual operation, coal is added to the transfer bottle 501 by removing the sealing cap 502, and the transfer bottle 501 is further sealed with the sealing cap 502 and embedded into the connecting seat 505 through the first insert tube 503. The two ends of the connecting seat 505 are sleeved on the second insert tube 504, thus completing the combination of the mixing seat 4 and the transfer bottle 501. After the coal transfer is completed, the first insert tube 503 can be pulled out to use the mixing seat 4 to further mix the coal. Coal is added to the mixing seat 4 in a distributed manner, which can avoid coal scattering and contaminating the mixing machine.
[0028] By controlling the limiting rod 605 to be embedded in the limiting seat 603 inside the first insert tube 503 and the second insert tube 504 respectively, the first insert tube 503 and the second insert tube 504 are further embedded in the connecting seat 505. By rotating the connecting seat 505, the material control seat 602 can be rotated in the filling seat 601. The gap between the first insert tube 503 and the second insert tube 504 will be opened, thereby allowing coal to be transferred between the mixing seat 4 and the transfer bottle 501. After the coal transfer is completed, the material control seat 602 will be reset under the action of the buffer spring 604. At this time, the mixing seat 4 and the transfer bottle 501 are separated, and the rubber stopper 608 is sleeved on the limiting rod 605.
[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
